Post surgery : Meckels Diverticulum.

My brother has undergone an abdominal surgery due to a sub acute interstitial obstruction involving the ileal loop in the right iliac. Doctors have removed the extra part from his stomach which was causing obstruction. It's been fifteen days and he is recovering very slow. Only half of the stitches are removed at this point. He is experiencing itching sensation at the affected area. Is this a common behaviour for this sort of surgery? Or should we consult any surgeon again? We are unable to get in touch with the chief surgeon who did the surgery. When we ask them his appointment, they would suggest to speak to general physician available at their hospital. Also, we have sent the removed part to biopsy and got the report. Can you please check the report and suggest if their would be any issue in future? My brother is a 24 year old guy now. Thanks in advance.
